ELECTRICAL CONNECTING-SOCKET.

Specification of Letters Patent.

Application filed March 19, 1915. Serial No. 15,680.

To all whom it may concern Be it known that 1, Jason C. STEARNS, acitizen of the United States, residing at WVorcester, in the county ofWorcester and State of Massachusetts, have invented a new and usefulElectrical Connecting-Socket, of which the following is a specification.1

This invention relates to a socket member for use in making electricalconnections.-

The mounting of these sockets in automobile lamps especially hasinvolved considerable trouble in the manufacture and assembling of theparts.

This invention is designed for the purpose of producing ,a constructionin which the usual metallic socket member can-be so'made that it can beapplied to the lamp casing and brazed or otherwise treated by heat, orin any other desired way, and yet the connecting parts at the back ofthe socket can be inserted in it and permanently fixed to it in a verysimple way without spoiling the finish of the socket member and itssurrounding parts, and without brazing or other operation that requiresthe reheating of the parts.

Reference is to be had. to the accompanying drawings, in which- Figure 1is a perspective View of a lainp socket member constructed in accordancewith this invention with the parts in a con dition assumed in the art ofbeing assembled; Fig. 2- is a similar view showing the device completed,and Fig. 3 is a sectional view of a head light showing another way inwhich the invention can be used.

The invention is shown in Figs. 1 and 2 as applied to a cylindricalmetallic socket member 10 adapted to hold an incandescent electric lamp11 in a well known way. This socket member is formed with a longitudinalslot 12 extending in from the end and having at its inner end atransverse slot 13 at one side. On the other side of the slot 12 is atransverse notch 14 located a slight distance nearer the end of themember than is the slot 13. This forms a circumferential tongue 15between the slot 13 and the end of the member and this tongue ispreferably provided with a rounded surface 16 at its outer side. Thistongue is capable of being bent outwardly in a transverse direction, asshown in F 1g. 1 audit 1s manufactured and supplied in that manner.

- A plug or connecting element 17 is shown having a pro1ect1on or pin 18for connect- 'slot 12, being guided in part by the sum ing it with thesocket member. bllng these two parts, the plug is int 111 such a mannerthat the pin 18 enter 7 16 if desired and is then pushed in nd turnedinto the notch 14. This having b on accomplished the tongue 15 is bentdown into'the position shown in Fig. 2 and the pin 18is thus permanentlyheld in p in. and the two parts 10 and 17 securely fired to gether. InFig. 3 the same construction shown as applied to a lamp casing mirror21. llHere the socket membe fixed to the casing and a plug 22 asdescribed in connection, with Figs 2. This plug is connected with the inthe usual manner." hromthis it seen that-this union oithe parts in avery simple and expeditious and without heating the parts in a; k sothat any surface finish with wh; h e parts may have been supplied isleft intact and there is no danger oi injuring them. Although I havesaid that the pa permanently united, it will beclear the i is desired todisconnect them at any illiud, that can be done simply by bending back{he tongue 15 and that even after iSG'tilill placements, the parts willnot be in ured and ill l.

will be fully effective for the purpose skilled in the art without departhe scope of the invention exp the claims. Therefore, I no not limitedto all the details herein shown and described, but

What I do claim is 1. As an article of manufactu' trical connectingsocket compris member having a notch therein and a (on; normally closingthe end of the not h l being capable of being bent out of l tion withthe notch, and a member 1 and fitting the socket member and ..a g aprojection adapted to enter said notch when the tongue is bent away fromit.

2. As an article of manufacture, an circtrical lamp socket compris .w'socket member having s a tongue projecting town 7 1 normally closing theend th normally lying within th face of the socket member but beingcapable of being bent transversely away from the notch so as to exposethe notch and a plug member entering the socket member and having a pinprojecting radially therefrom and adapted to be located in the notchwhen the tongue is bent into the cylindrical surface of the socketmember.

3. As an article of manufacture, a cylindrical socket having a slotextending in 1011- gitudinally from one end and provided at its end witha circumferential transverse slot on one end and with a transverse notchon the other near the end, the transverse slot forming acircumferentialtongue between it and the end of said socket member,Wherebyxsaid tongue can bebent an ay from the notch to open it and canbe benttoward it to close its end.

In testimony whereof I have hereunto set my hand, in the presence of twosubscribing Witnesses.
